Use the video feature on your smartphone to walk through your home room-by-room and pan over your belongings. Include an audio commentary noting any significant items, and capturing any info about quantity, age, or price that seems relevant. Open cabinets, drawers, and closets to record those contents, and remember to review your basement and garage storage, too.
You can find several home inventory apps online, including Know Your Stuff created by the Insurance Information Institute. These apps help you track more detailed information, including model and serial numbers, photos, and scans of your receipts and appraisals. Some apps include reporting features that allow you to export your data to PDF or Excel—ideal if you ever have to report a loss.
If you’re not a smartphone user, or you just prefer the tangible nature of paper records, you might like the home inventory checklist from the National Association of Insurance Commissioners. This printable form helps walk you through the main rooms of your house and includes reminders for miscellaneous items you’ll want to record.
